This invention relates to improvements in hay stackers and more particularly to, improvements in the stacker teeth.

The invention seeks, among other objects, to provide an improved hay-retaining finger for stacker teeth of such nature that the teeth may readily move beneath the hay while after the hay is positioned on the teeth and the teeth are swung upwardly, the retaining fingers will prevent the hay from accidentally slipping off the teeth.

The invention seeks, as a further object, to provide a retaining finger of simple construction as well as novel means for connecting the finger with a stacker tooth.

And the invention seeks, as a still further object, to provide a retaining finger well adapted for use in connection with different makes of hay stackers.

Other and incidental objects of the invention not particularly mentioned in the foregoing will be apparent during the course of the following description.

In the drawing, Figure 1 is a fragmentary plan view showing certain of the teeth of a hay stacker equipped with my improved finger,

Figure 2 is a fragmentary elevation of one of the fingers, parts being shown in section, this view illustrating the finger extended in active position,

Figure 3 is a view similar to Figure 2 showing the finger folded,

Figure 4 is a transverse sectional view on the line 44 of Figure 2,

Figure 5 is a detail perspective view showing the hinge loop of the finger, and

Figure 6 is a detail sectional view showing a slight modification of the invention.

Referring now more particularly to the drawing, I have shown a number of stacker teeth at 10. Usually, these teeth are formed of wood and are tapered towards their forward ends, each of the teeth being provided at the tip thereof, as particularly seen in Figure 2, with a convex upper face 11. In equipping the teeth of a stacker with the present invention, it has been found unnecessary to provide all of the teeth with the improved retaining finger and accordingly, in Figure 1, only two of the fingers are illustrated. Any suitable number of the fingers may, however, be employed, as found most effective.

Referring now particularly to Figure 2, it will be seen that the finger shown is provided at the base of its convex face with a transverse groove 12 traversing the upper face of the finger and formed in the finger in the rear of said groove HAY-RETAINING FINGER FOR TEETH is a medially disposed recess 13 gradually t,a- I

pered towards its forward end. Mounted to rock in the groove 12 is an oblong retaining finger 14. This finger may be struck from suitable sheet metal and the side edges thereof arec'urved towards each other at the forward end portion of the finger to provide a' pointj15 while, at its rear end, the finger is curved slightly, as indicated at 16, and is cut away-at opposite "sides thereofto define a-hinge loop 17 flanked at it's base by stop shoulders 18. Extending through the hinge loop 17 is a split rectangular link 19 which snugly embraces the sides of the stacker tooth 10 while the overlapping abutting ends 20 of said link are pressed into the wood of the tooth at its lower edge. Thus, the link is securely engaged with the stacker tooth and pivotally supports the finger 14 to rock within the groove 12. As shown in Figure 2, the finger is movable upwardly to active position when the shoulders 18 of the finger will abut the sides of the link 19 for limiting the finger in its pivotal movement and rigidly supporting the link to incline upwardly and rearwardly with respect to the tip of the tooth. On the other hand, the finger may swing rearwardly and downwardly, as shown in Figure 3 to lie against the upper face of the tooth.

Seated at one end in the recess 13 of the stacker tooth is a fiat spring 21 and extending through said spring and through the stacker tooth are spaced nails 22 or other approved fastening devices firmly connecting the spring with the tooth. The opposite end portion of the spring isfree to coact with the finger 14 at its rear side so that this spring will normally urge the finger to active movement of the fingers will be augmented by the springs 21. Accordingly, the fingers 14 will then prevent movement of the hay outwardly along the teeth so that, when the teeth are swung upwardly for depositing the hay upon a stack, accidental loss of the hay will be prevented.

In Figure 6, I have shown a slight modification of the invention wherein, in lieu of the link 19, I

employ an attaching link in the form of a U-bolt 23, the bolt being shown in position on a stacker tooth 24. As will be observed, the bolt 23 is' necessary.

Havingthus described the invention, I claim:

1. The combination with a stacker tooth, of a link embracing the tooth, and a hay-retaining finger pivoted upon they link at the upper side of the tooth and provided with a shoulder to coact with the link for limiting the finger in its upward swinging movement away from the tooth.

2. The combination with a stacker tooth, of a link embracing the tooth, a hay-retaining finger pivoted upon the link at'the upper side of the tooth and provided with a shoulder to coact with the link for limiting the finger in its upward swinging movement away from the tooth, and a spring fixed to the tooth and urging the finger upwardly. J

" 3 The combination with a stacker tooth, of a split link embracing the tooth, and a finger provided at one end thereof with a hinge loop embracing the link and pivotally connecting the finger thereto for upward swinging movement away from the tooth, the finger being formed at said end thereof with a shoulder to coact with the link for limiting the finger in its upward swinging movement.

4. The combination with a stacker tooth, of a link embracing the tooth, and a retaining finger cut away at one end thereof to define a hinge loop having shoulders at opposite sides thereof, the loop embracing the link and pivotally connecting the finger thereto for upward swinging movement away from the finger, said shoulders being disposed to engage the link for limiting the finger in its upward swinging movement.

5. In a haystacker, a tooth provided near its outer end with a transverse groove at the upper side of the tooth and in the rear of said groove with a recess, a link embracing the tooth at said groove, a finger provided at one end with a hinge loop embracing the upper side of thelink within said groove and pivotally connecting the finger with the link to rock-upwardly and forwardly with respect to the tooth, shouldersformed on the finger tocoact with the sides of the linkfor limiting the finger in its upward swinging movement, and a spring fixed atone endto the tooth in said recess and free at its opposite end to coact with the finger for urging the finger upwardly.
